Abstract
The utility model relates to a support piece of rotor pole coils of a synchronous salient pole motor. The support piece comprises a motor rotating shaft, pole coils, and a supporting piece, wherein the supporting piece is an elastic body, and is fixedly connected with the motor rotating shaft and always elastically contacted with adjacent two pole coils. Since the supporting piece is the elastic body and is elastically contacted with the adjacent two pole coils, pressure is always elastically supplied to the adjacent two pole coils, safety running of the support piece is guaranteed, especially, a hollow steel structural member can provide large elastic force, and can provide large pressure to the coils, and meanwhile, the hollow structure can provide a cooling medium passageway for radiation of the rotor pole coils, and the problem that the rotor pole coils are difficult in radiating is solved. The utility further relates to the synchronous salient pole motor.
Description
Technical field
The utility model relates to field of motor manufacturing, relates in particular to a kind of strutting piece and synchronous salient pole machine of synchronous salient pole machine rotor magnetic pole coil.
Background technology
At present, four utmost points or the four extremely supporting piece structure of the pole coil of above synchronous salient pole machine rotor mostly are steel plate flanging structure greatly, steel plate flanging structural support places between rotating shaft and the pole coil, this steel plate flanging structure often can only provide an initial pressure to pole coil, motor is after operation a period of time, because its elasticity is less, often cause the diffusing circle between pole coil, have a strong impact on the safe operation of motor, in addition, this supporting piece structure, the heat of pole coil is difficult to shed, and causes the rotor temperature rise higher.
The utility model content
First purpose of the present utility model is, a kind of strutting piece reliable, that be beneficial to the synchronous salient pole machine rotor magnetic pole coil of ventilation and heat that supports is provided, and second purpose of the present utility model provides a kind of synchronous salient pole machine that comprises the strutting piece of this rotor magnetic pole coil.
In order to realize first purpose, the utility model provides a kind of strutting piece of synchronous salient pole machine rotor magnetic pole coil, it comprises machine shaft, pole coil, strutting piece, described strutting piece is elastomer, described strutting piece is fixedlyed connected with machine shaft, and all the time with two neighboring pole pole coil Elastic Contact.
Preferably, described strutting piece is interior cross section and the concentric cored steel structural member in outer cross section, the section thickness of strutting piece and two neighboring pole pole coil contact position and strutting piece and machine shaft contact position is symmetry equivalent, thereby it is close to contact pressure between strutting piece and two neighboring pole pole coil and strutting piece and the machine shaft.
Preferably, the outer cross section of described strutting piece is regular polygon, and described polygon is 4 multiple.
Preferably, the interior cross section of described strutting piece is regular polygon, and the regular polygon in described interior cross section is similar to outer cross section regular polygon.
Preferably, the interior cross section of described strutting piece is circular.
In order to realize second purpose, the utility model also provides a kind of synchronous salient pole machine, and it comprises the strutting piece of salient pole machine rotor magnetic pole coil, and the strutting piece of described salient pole machine rotor magnetic pole coil is the strutting piece of above-mentioned salient pole machine rotor magnetic pole coil.
Technique effect of the present utility model is, because strutting piece is elastomer, with two neighboring pole pole coil Elastic Contact, pressure is provided for all the time two neighboring pole pole coil elasticity, guaranteed the safe operation of coil, particularly, the steel construction piece of hollow can provide bigger elasticity, can provide bigger pressure to coil again, simultaneously, hollow structure has solved the problem of rotor magnetic pole coil heat radiation difficulty for the heat radiation of rotor magnetic pole coil provides coolant guiding channel.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing implementation process of the present utility model is described further.
With reference to accompanying drawing 1, be four utmost point salient pole synchronous electric machine rotor magnetic pole coils, 3 strutting pieces, 1 schematic diagrames, it comprises machine shaft 2, pole coil 3, strutting piece 1, pole shoe 4, pole bolt 5, strutting piece 1 is the cored steel structural member, strutting piece 1 and two neighboring pole pole coil I 3-1, pole coil II 3-2 is Elastic Contact all the time, strutting piece 1 is fixedlyed connected with machine shaft 2, the outer cross section of strutting piece 1 is similar positive eight limit polygons with interior cross section, the wall thickness unanimity on each limit, like this, strutting piece 1 and the two poles of the earth pole coil I 3-1, between the pole coil II 3-2 and to contact pressure between strutting piece 1 and the machine shaft 2 close, pole shoe 4 is connected with machine shaft 2 by pole bolt 5, during assembling, guarantee the decrement of strutting piece 1 by the difference in height between adjustment two neighboring pole pole coil I 3-1 and machine shaft 2 and pole coil II 3-2 and the machine shaft 2, and when moving, motor also keep certain decrement to satisfy the two poles of the earth pole coil I 3-1, the requirement of the required pressure of pole coil II 3-2, simultaneously, coolant passes through the hollow section of strutting piece 1, thereby reaches the requirement of pole coil 3 heat radiations.
The utility model also provides a kind of synchronous salient pole machine, and it comprises the strutting piece 1 of salient pole machine rotor magnetic pole coil, and the strutting piece 1 of described salient pole machine rotor magnetic pole coil is the strutting piece 1 of above-mentioned salient pole machine rotor magnetic pole coil.Because the strutting piece 1 of above-mentioned salient pole machine rotor magnetic pole coil has above-mentioned technique effect, the synchronous salient pole machine with strutting piece 1 of this salient pole machine rotor magnetic pole coil also should possess corresponding technique effect, introduces no longer in detail at this.
More than be a kind of execution mode of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described execution mode.The technical scheme of all and present embodiment equivalence such as the hollow section of strutting piece 1 be circle, all belong to protection range of the present utility model.
